Abstract

Many individuals are not only food insecure but chronically exposed to high levels of mycotoxins through their diets in many developing countries Seventy composite samples of stored maize grains were collected from farmers’ storage structures in five agroecological zones AEZs of Nigeria where maize is predominantly produced between August 2011 and February 2012 The grains were analysed for mycotoxin contamination with the liquid chromatography tandem mass spectrometry method and mycotoxin occurrence maps constructed from the database of the distribution of the toxins A risk assessment was also carried out in order to provide information on the extent of human exposure to the toxins Twelve regulated mycotoxins with negative economic and public health consequences were detected in the maize grains across the AEZs at concentrations exceeding the maximum allowable limits including AFM1 that was detected for the first time in Nigerian maize There is a high risk of contamination of the stored grains by Nigerian consumers especially in the Derived and Southern Guinea Savannas resulting in a national burden of between 12685 and 3868229 DALYs Intervention strategies are therefore needed across the AEZs to ensure that safe and wholesome foods are made available to the populace
